A) \[\frac{1}{\sqrt{2}}\]
B) \[\sqrt{2}\]
C) \[2\sqrt{2}\]
D) 2
Correct Answer: A
Solution :
\[v=\sqrt{2gR}\]Þ \[\frac{{{v}_{p}}}{{{v}_{e}}}=\sqrt{\frac{{{g}_{p}}}{{{g}_{e}}}\times \frac{{{R}_{e}}}{{{R}_{p}}}}=\sqrt{2\times \frac{1}{4}}=\frac{1}{\sqrt{2}}\] \ \[{{v}_{p}}=\frac{{{v}_{e}}}{\sqrt{2}}\]
